IMPROVEMENT IN LAMP-WICKS.

Specification forming part of Letters Patent No. 115,045, dated May 23,1871.

To all whom it may concern:

Be it known that I, JOHN FARRELL, of Brooklyn, in the county of Kingsand State of New York, have invented and made an Improvement inLamp-Wicks; and the following is declared to be a correct descriptionthereof.

Lamp-wicks are usually made either flat or round, and of a length toreach the oil or hydrocarbon liquid in the reservoir. Considerable ofthe wick is always wasted, because the length of the same must always besufiicient to reach from the wick-tube to the fluid when at the lowestlevel to which it is to be burned.

I have discovered that, with coal-oils and other limpid hydrocarbonliquids, it is not necessary to have the wick itself extend down to theliquid, or be prolonged by a stationary wick of the same size as itself,but that a capillary cord, extending from the lower end of the wick intothe burning fluid, will supply sutficient of said fluid to the wick forthe purposes of combustion.

My invention therefore relates to a new article of manufacture,consisting of a lampwick with a capillary cord or cords extending fromits lower end. This article can be made much cheaper than the wicksheretofore employed, because there is a saving of the fibrous material.The entire wick can be used so long as the body of the wick will extendfrom the end of the wick-tube to the wick'raising device in the burner,and the supply of the fluid, being through such cords, will be uniform,and there will not be either an unsightly wick filling a smallreservoir, or the risk of the end of the wick bending up out of thereach of the oil, because the thin cord willhang down of its own weight.

In the drawing I have shown an elevation of my said wick, the upper parta being either flat or circular, and the capillary cord or cords 1)extending from the lower end of such wick. I prefer to use two capillarycords, b, with a flat wick, the same extending from the edges of thewick.

I claim as my invention- The lamp-wick, made with a capillary cordextending from its lower end,as a new article of manufacture.

Signed by me this 31st day of March, A. D.
